100 stand-alone power systems across WA


Western Australia has reached a major milestone as 100 stand-alone power systems are now deployed on the state’s main power grid, improving reliability and power quality for regional and remote customers.

The units are powered by solar panels and a storage battery, and include backup diesel generation, which provides cleaner, more reliable power.

This innovative green solution is a safer alternative to traditional poles and wires.

Stand-alone power systems (SPS) are particularly beneficial for regional customers, where supply costs are high and power reliability is affected by distance, terrain, and severe weather.

SPS are now located in many locations across the Midwest, Wheatbelt and Great Southern, with the last being installed after the Shackleton bushfire in early 2022.

A recent Western Power customer research report revealed high levels of satisfaction with the SPS.

Participating customers rated their overall satisfaction at 8.2 out of ten (ten being “excellent”), while their satisfaction with the post and wire connection, prior to the SPS, was less than 6.7 out of ten.

Western Australia Energy Minister Bill Johnston said: “The McGowan government is committed to a greener and cleaner energy system, which is why we will deploy 4,000 systems stand-alone power stations across the state over the next ten years.

“Western Power’s survey is an excellent result, with more than 75% of customers saying they would likely recommend stand-alone power systems to others.

“The research also indicated that renewable energy was important for rural customers, with a third of participating customers already using solar power and believing it was the way of the future.

“There are 90 SPS currently deployed by four Western Australian suppliers, creating new industry and jobs for locals, and replacing approximately 330km of overhead lines.”
